Joint replacement: a high-risk setting
Major orthopaedic procedures — above all hip and knee total joint replacement — are among the operations with the highest risk of venous thromboembolism (VTE). Three factors of Virchow's triad coincide: pronounced tissue trauma, an altered coagulation state and sometimes prolonged immobilisation in the postoperative phase. The S3 guideline on VTE prophylaxis (AWMF 003-001) therefore classifies these procedures as high-risk.
Mechanical and pharmacological — not either/or
In the high-risk range, guidelines usually recommend pharmacological prophylaxis, often combined with mechanical measures following a risk assessment. Intermittent pneumatic compression (IPC) is the active, mechanical component: it promotes venous return through cyclic compression of the garments and counteracts blood stasis without interfering with coagulation. How the procedures fundamentally differ is explained under mechanical vs. pharmacological thromboprophylaxis.
When IPC is especially relevant in orthopaedics
- Increased bleeding risk: when (full) pharmacological prophylaxis is not justifiable, the mechanical measure comes to the fore.
- Early postoperative phase: IPC can be used immediately after surgery while patients are still immobile.
- Adjunctive in the high-risk setting: in addition to pharmacological prophylaxis after a medical risk assessment.
The indication and the choice of measures are always made by the treating physicians. Recognised limits of the procedure are on the page on IPC contraindications.
Practical implementation on the ward
For the orthopaedic ward routine, it matters that mechanical prophylaxis is reliably available and simple to apply. The mobile IPC systems of the Phlebo Press® technology — the Phlebo Press® DVT 650 Easy and the Phlebo Press® DVT 603 — control the pressure automatically, operate quietly and are delivered with device instruction under §83 MPBetreibV.
Frequently asked questions
Why is the thrombosis risk in orthopaedics particularly high?
Major orthopaedic procedures such as hip and knee replacement are among the operations with the highest risk of venous thromboembolism (VTE). Tissue trauma, prolonged immobilisation and activation of coagulation coincide. The German S3 guideline (AWMF 003-001) therefore classifies these procedures as high-risk.
Is prophylaxis in joint replacement mechanical or pharmacological?
In the high-risk setting a pharmacological prophylaxis is usually used, often combined with mechanical measures. IPC is a mechanical option — adjunctive to pharmacological prophylaxis or as the sole measure when medication is contraindicated. The decision is made by the treating professionals after a risk assessment.
When is IPC useful in orthopaedics?
Particularly when an increased bleeding risk argues against (full) pharmacological prophylaxis, in the early postoperative phase, or as an addition in the high-risk setting. IPC works purely mechanically and does not affect coagulation.
